Description

Technical field [0001] The invention relates to a circuit for realizing wireless network card interface communication, in particular to a circuit design that uses a programmable logic device CPLD to realize communication with a PCMCIA wireless network card interface. Background technique [0002] With the improvement of office conditions and the development of large-scale integrated circuit technology, various notebook computers have been widely used due to their convenient portability and flexible use. The same as the USB interface, the PCMCIA interface is almost one of the necessary interfaces for all notebook computers. Its main function is to insert the PCMCIA wireless network card to support the realization of random access to the wireless LAN. [0003] At present, the wireless local area network (WLAN for short) based on the 802.11 protocol technology is mainly used, and the wireless channel is used as the data file transmission medium. In view of the application of existin...
